SLICING-MACHIN E.

Specification of Letters Patent.

Application filed .Tanuary 4. 1919. Serial no. 269.637..

To all whom it may concern Be it known that I, ERNEST K. I-Ioomlacitizen of the United States of America, residing t Indianapolis, in thecounty of Marion and State of Indiana, have invented certain new anduseful Improvements in Slicing-Machines, of which the following is aspecification.

The object of my invention is to provide a combined power and handdriven outfit which can be easily operated and is compact and efficient.

In the drawings Figure 1 is a plan;

Fig. 2 a cross section of the clutch mechanism;

Fig. 3 a plan of a portion thereof and Fig. 1 an elevation and sectionof the motor and gear reduction.

The numeral 1, represents, a standard slicing machine of thereciprocating carriage type which is well known in the trade. Thismachine carries a rotary knife 2, a reciprocatin carriage 3 and afeeding mechanism 1. Hrimarily the machine is operated by hand wheel 5,mounted on a shaft 6. Power is transmitted through this shaft and atrain of gears to the knife and carriage. As the knife rotates and thecarriage reciprocates, the feed mechanism feeds the meat or material tobe out, toward the plane of rotation of the knife the predeterminedthickness. This construction is old and well known.

Mounted on the machine 1, is an electric motor 7 having the usualarmature shaft 8 which carries a coupling plate 9. This coupling late isprovided with the usual flexible d1sk 10 which drives a worm 11, meshingwith a worm wheel 12 carried in a housing 13. This housing 13 is securedto the base of the machine as shown at 14. Vorm wheel 12 is mounted onthe end of a quill 15, which carries at its other end the male member16, of a friction clutch.

This quill 15 is loosely mounted on the end of the machine knife drivingshaft 17, which carries at its outer end a sprocket18, which drivesknife 2. This shaft also carries a car 19 which meshes with a gear 20carrie by shaft 6.

Splined to shaft 17, is the female member 21, of the friction clutch.This is adapted to slide on shaft 17, and either contact with or.disengage from the member 16.

A slot 22, is cut through shaft 17 and also through clutch part 21, andthrough this slot is a drive key 23. Extending through a hole 241 inshaft 17, is a rod 25, rigidly secured to key 23, and carrying at itsouter end a washer 26 in contact with a spring 27, resting on a ballbearing 28, carried in a pocket in the quill.

Mounted in housing 13 concentric with shaft 17 is a threaded stud 29carrying a hand wheel 30. This stud 29 is adapted to contact with rod25.

The operation of the device is as follows: When it is desired to drivethe machine electrically, the hand wheel 30 is turned so as to releasestud 29 from rod 25. This allows spring 27 to draw the clutch member 21,in contact with clutch member 16, thus providing a driving connectionbetween the motor and the knife driving shaft 17, through worm ll, wormwheel 12, quill l5, clutch 16, clutch 21 and driving key 23. Thus theentire driving mechanism rotates and the machine is driven.

Now when it is desired to stop the machine, the hand wheel 30 isoperated so that stud 29 pushes against rod 25, compresses spring 27,and at the same time pushes clutch member 21 out of contact with member16, thus entirely releasing shaft 17 from driving connection with themotor.

It will be noted now that if the machine is operated by means of thehand wheel 5, shaft 17 is driven by gear 19 and clutch member 21 rotatestherewith; rod 25 also rotates as does washer 26, spring 27 and ballbearing 28. The quill stands still however and this allows handoperation of the machine without operating the motor driving parts.

In order to limit the throw of hand wheel 30, I provide a stop pin 31,and a plunger 32, which allows 1 turn of the hand wheel which is amplefor all practical purposes. I also provide a felt washer 33 to preventthe oil in gear housing 13 from working along the quill.

I claim 1. In a slicing machine; a friction clutch and ear reductionconsisting of a shaft; a member of said clutch being splined to saidshaft, a quill mounted on said shaft and earrying'the other member ofsaid clutch; a gear carried by the other end of said quill; a rodextending through said shaft and connected to the splined member of theclutch;

Patented July 29, 1919.

copies of this patent may be obtained for nected to the splined memberof the elutch;

a ball bearing and spring interposed between said rod and quill; andmeans for operating said rod longitudinally substantially as and for thepurpose set forth.
